MACHINE FOR IMPREGNATING FABRICS WITH FLL JID SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 768,059, dated August23, 1904.

Application filed '.p:l; 30, 1902.

To all whom it may concern:

the county of Albany and State of New York,

have invented new and useful Improvements in Machines for ImpregnatmgFabrics Wlbll Fluid Substances, of which the following is aspecification.

This invention relates to a machine for impregnating woven fabrics withsubstances and compounds when in condition 'of a fluid; and it consistsof certain novel features and combinations and arrangements of partsherein-. after described, and set forth in the claims.

The objects and advantages of this invention. will be clearly understoodfrom the specifica tion and claims whentaken in connection with thedrawings, (in two sheets,) in which- Figure 1 is a plan .view of amachine embodying the improvements in this invention.

.Fig. 2 is a front view of the operating parts of the machine. Fig. 3 isan end elevation of Fig. 4 is a sectional elevation, and Fig. 5 is asection illustrating the relative arrangement with the rubber-cylindershaft of adjuncts thereto.

Similar characters of reference refer to similar parts throughout theseveral Views.

In the drawings, A is the frame of the machine, which frame may be .ofany suitable form of construction adapted to receive and hold theseveral operating parts of the ma chine. Y

B and B are elastic exterior cylinders made of rubber of suitablethickness, as, say, one inch or more or less, and of equal diameters.

These cylinders B B are each suitably mounted and fixed on an interiorcylinder 0, which latter respectively are mounted on shafts C 0 One ofthese shafts, and preferably shaft C, is supported from fixed bearingsD, se-

' cured to the frame, while the shaft C is supported in adjustablebearings D, which latter respectively are provided with a suitable postd, which nicely fits in sleeve d, made I fixedly connected with eachbearing D, so that said adjustable bearings D may at pleasure be movedtoward fixed bearings D and be held at place moved to and therebyincrease the pinch of rubber cylinders BB or lessen Serial No- 105,32l.(N0 model.)

, the same, as may be found to be advantageous Be it known that I, HENRYA. MANN, a citizen of the United States, residing at Albany, in

by reason of the character of the fabric and the nature of the fluidsubstance being applied to the former and quantity of the same to betion to bearings D, yet I at present prefer to employ lugs E, suitablyconnected with frame A and'having in them the screw-threadedperforations e, in which work set-screws 0, provided with suitable heads6 adapted to receive a suitableinstrument for convenience for revolvingsaid set-screws in either d1rect1on in one direction forforcing therubber cylinder B toward its coacting rubber cylinder B,

C. and relatively back from a' vertical line drawn through the center ofshaft 0, so that the front surface of the rubber cylinder B may berelatively rearward of the line of axis 0 of shaft C of the lattercylinder. The purpose of this relative arrangement of the two cylindersB B will be hereinafter explained.

These cylinders B B are made-with equal diameters, so as to have equalsurface travel when in operation, and are simultaneously revolved bycog-wheels F F of like diameters and mounted on'their respective shaftsC 0 Cog-wheel F is actuated by cog-wheel F,-and this latter is actuatedby drive-pinion F.

G is a fixed spindle rigidly secured to frame A by its inner end 9,while its body is projected outward, as indicated by dotted linesparallel with H, so as to revolve the latter, and I is a loose pulleyrevolving on said hollow shaft, or it may be mounted on the outer endportion of the fixed spindle G, so as to revolve on the same, as may bepreferred. A suitable beltin Fig. 2 and shown in Fig. 5.

shifter (not shown) may be provided for shifting a driving-belt. (Alsonot shown.)

J and J are side plates which are arranged one at each side in themachine and between ends of said rubber cylinders and the respectiveside members of frame A. These side plates may be of any suitablenon-corroding substance, yet I prefer to make them of heavy plate-glassof thickness of one-half of one inch or more or less. These side plateshave both their inner and outer surfaces uniformly evenand smooth and onparallel planes and are respectively provided with suitable holes 1' ofdiameter corresponding with that of shafts C of rubber cylinder B, so asto freely receive the same, and also with holes j of diameter and ovalform to freely receive the shaft C of rubber cylinder B. Theseperforations j and j are indicated by dotted lines These side plates J Jare made with width greater than the diameter of the rubber cylinders BB and have their lower ends made preferably with straight lines of edgef, as shown in Fig. 4. The ends 6 b of rubber cylinders B B abut theinner surfaces of said side plates, while the interior cylinders C aremade shorter than said rubber cylinders by, say, one quarter of an inchor more or less, so that their ends will not have contact with said sideplates. These side plates J J are clamped from their outer sides byclamping-plates K K, held up to the outer sides of said side plates bysleeves L L, which respectively abut bearings D and D andclamping-plates J J, as shown in Fig. 2, so as to crowd the latteragainst the outer sides of side plates J J and cause the latter to becrowded against the abutting ends of said rubber cylinders B B, asillustrated in Fig. 5. This above-described construction and arrangementof parts (shown in Fig.5) produces a tight joint between the ends of therubber cylinders and the side plates, so that none of the fluidsubstances operated with can have passage from the surfaces of therubber cylinders B B to the shafts C (I and bearingsof the latter.

L is a receptacle for containing the fluid substance which is to beoperated with for impregnating fabrics subjected to the operations ofthis machine.

L is a platform for supporting the receptacle in place above the upperrubber cylinder B from the frame A by means of suitable brackets L Thisreceptacle may be of any suitable form and capacity, and is providedwith a suitable device through which the fluid substances may bedischarged on cylinder B in quantity and place preferred or found to beadvantageous.

Although in the drawings is shown an ordinary form faucet Z, connectedwith said receptacle from its bottom and provided with a discharge-spout1, indicated in Fig. 1 by dotted lines as being of a relatively smallsize,

which is adapted to limit the area of discharge.

of the fluid on cylinder B, yet this dischargespout may be of form andwith an extension of its discharge that may be adapted to extend thedischarge of the fluid to that cylinder throughout its whole length, asshown at 1 in Fig. 2, or as may be found to be advantageous.

M is a feed-table suitably supported from the frame A, preferably bymeans of brackets M. The front edge of this table is relatively at nearopposite the line of pinch of the cylinder B B.

N is a receiving-table supported by brackets N, connected to frame A andadapted to receive the articles as they emerge out from between thecylinders B B.

O is a shallow receptacle for receiving the fluid substance which mayfrom any cause come to be in such excess on lower cylinder B as to dripfrom the'same. This receptacle is removable at pleasure, and is shown tobe supported beneath lower cylinder B from suitable supports 0 0, Fig.4c.

This machine may be constructed with its sizes and proportions of partsvariously modified as the nature of its service may require" that is tosay, the cylinders may have their diameters and lengths respectivelyincreased or lessened, as may be found to be advantageous for operatingwith a full belt or roll of fabric in its full width, with pieces ofnarrow width, and with articles such as collars, cull's, &c.ofrelatively short lengths as compared to that of webs of woven fabric.

The manner in which this machine is operated is as follows: Thereceptacle L is supplied with any prepared quantity of the iiuidsubstance which is to be used for impregnating the fabric to be operatedwith, whether it be in character starchy, viscid, coloring,waterproofing, fireproofing, or of other natu re, which is adapted togive to the fabric or article some peculiar quality not natural in thefabric. The machine will be started, so as to revolve the cylinders B Bin proper direction,and the discharge device will be regulated fordelivering the fluid substance on one of the said cylinders, preferablyon the upper one, to such a length on the same as may be preferred. Theoperator will doliver the fabric or article from off the feedtable tobetween the two revolving cylinders and at the line of pinch of thesame, when the revolving cylinders will move the fabric or article indirection from said feed-table to the receiving-table, from which itmaybe delivered into a suitable receptacle (not shown) or be removed byhand, as may be found to be advantageous.

The side plates J J, against the inner sides of which the ends ofcylinders B B abut, having such a close or tight joint with said ends ofthose cylinders operate to prevent the fluid substance operated withfrom passing outward to have contact with the outer surfaces of theextended end portions and journals of the shafts of said cylinders, and,being made of glass, these side plates will not corrode and therebydiscolor the fluid substance v admits this machine being used forimpregnating fabrics with substances which may be of alkaline or acidcharacter.
